VU meter lamps burned out. How to change, what is replacement lamp? How about a service manual?

wow very old van.
so engine runs car drives ok , right, just head lamp problems.
HL flasher work or not, (hi beam flash switch)??????
in HIGH beam mode is cluster hi lamp glowing?
no? fuse is blown.
well a volt meter finds the cause most easiest.
and schematic from the service manual.
telling what engine or VIN first, is best
or the wrong fuse boxes are seen,, ok>?
you checked fuse but forgot this van has lots of fuesible links. like this super simple schematic shows.
nothing can be more simple, no BCM computer mess.
it can only be 5things (engine runs)

1. fuse link
2. dimmer
3. HL switch
4. both lamps burned out, nah
5. grounds to both lamps cut/rusty.

if both lamps lugs are at 12vdc, the ground is dead

Rear-Projection TVs have a lamp, which picks up the picture and projects it on the TV screen. A burned-out or connected lamps are two of the most common problems for Rear-Projection TVs. First, you will want to confirm the bulb is still good. If the bulb is bad then then replace it immediately. Second consult your user manual and verify the lamp and lamp cover are installed properly. Most Rear-Projection TVs have warning light which notify you when there are lamp problems. Again consult the user's manual to see what each light means.

select the menu - default - clear lamp hour meter to reset lamp usage hours.
Note when the lamp exceeds 2100 hours (3100 in Eco mode) the projector cannot turn on and the menu is not displayed if this happens do the following while in 'standby' to clear values for Remaing lamp Time and lamp hour meter for vt670/470 press the help button on remote control for a minimum of 10 secs When the lamp clock is reset to zero the lamp indicator goes out.

turn your tv on. on the tv it self press and hold the " - " like your turing it down. then on your remote press and hold the number " 0 " for five seconds. it should say the the meter has been reset to zero.

if you don't know exactly how many hours are on the new lamp, you can't be sure it works. since it's a mercury lamp, there will be no contenuity. check the lamp for cracks or clouding, not just burn marks.if the lamp is actually good, you may have a ballast issue.

This should work:
